HOTBISTS SERVICE-RECORDING DVICE.

IApplication led March 21, 1925. Serial No. 17,186.

An object of the invention is to provide an improved recording device ofinexpensive and simpliied construction, including a number of recordingor indicating devices mounted and arranged in a supporting enclosure andsettable to record or indicate the mileage that the automobile hadtraveled when certain work had been performed or adjustments had beenmade upon parts of lo the automobile. By use of a device of thischaracter the owner or driver of the automobile niay maintain aconveniently settable and visible indicator of desirable or essentialdata, whereby he will be enabled to keep l5 himself informed as to factsthat might otherwise be overlooked and result in damage to the vehicle.i

Another object of the invention is to provide an improved recordingor'indicating device possessing the advantageous features ofconstruction and mode of operation herein described, reference beingmade to' the accompanying drawing, in which Fig. 1 is an elevationshowing the face of 25, the device and the indicating instrumentalitiestherein.

Fig. 2 is a side edge elevation with parts of the -casing broken away todisclose the arrangement of the indicating devices. U

Fig. 3 is a cross sectional view on the line 3-3 of Fig. l.

In the embodiment of the invention shown the casing comprises a plateshaped to provide a front wall 1, sideiedge walls 2, and upper and lowerend walls 3. The casing is completed by a wall 4 enclosed within themargins of the side and end walls and secured thereto and preferablypossessing the characteristics of resiliency and flexibility.

A number of vertical series of horizontal slots 5, each of which has anumber of pairs of vertical notches 6 extending from its upper and loweredges, respectively, are -formed in the front wall or face plate 1.

To each of the side edge walls 2 an angular late 7 is attached by rivets8 passing hrough said walls and one of the angular ortions of saidplates, while the other angul)ar portions of said plates extend inwardlyagainst the inner side of the plate 4 (Fig. 3)

Each of the plates 7 has an inwardly offset arm 9 for each 'of theadjacent slots 5 and in said arms 9 the shafts 10 are mounted.

The indicators are independently rotative on the shafts 10, each ofsaidindicators comprsing a barrel or cylindrical portion 11 andrespective parts 11 to which they are attached and operate within thenotches 6. Each disc 12 is formed with v a peripheral series of notches13 corresponding in number to the number of digits on the part 11 anddesigned and adapted to be engaged byV any suitable implement or by thefinger to turn the indicator from one adjustment to another. The wall 4is shaped to provide a projection 14 for each disc, which projectionsengage in the notches 13 and hold the indicators :from accidentalturning, but, due to the resilient and lexiblecharacter of the plate 4,permit the indicators to be turned as previously stated.

The device maybe mounted in position for convenient visibility indifferent ways, as by providing a threaded stud 15 to extend through asupportingpart and receive a nut; or, the device may be supported by ahanger extension 16 arranged to engage over a support, or both of 'saiddevices may be employed.

The device may be made of such capacity as to maintain a constant recordof all essential data needed in the proper maintenance oi the'automobile. As shown there are a set of dials indicating the mileage atwhich a new tire was mounted on each wheel. There are also sets of dialspertaining to the engine; one set indicating the mileage at which thecrank case was drained and refilled; another set indicating the mileageat Which the carbon was removed; another set indicatin the mileage atwhich the valves were groun while the remaining sets of dials maintain arecord of other mileage changes. The Jface plate contains notations toindicate the func-y tions of the respective indicating devices.

I am aware that the invention ma be varied structurally withoutdeparture rom the nature and principle thereof. I do not restrict myselfunessentially, but what I claim and desire to secure by Letters Patentis 1. A device ofthe character described comprising a casing front wallhaving a series of transverse slots, a resilient casing back wall, sideand end walls connecting the comprising a .casing composed of a frontWall having series of transverse slots, a resilient plate forming theback Wall of the cas- 15 ing andhaving series of pro'ections thereonopposite said series of slots, s afts supported in the casing oppositesaid slots, series of indicating devices mounted on said shafts andarranged to display rows of digits 20 through said slots respectively,and provided with peripheral indentations engaging said projections onsaid late.
